Abstract:I will discuss the nonequilibrium dynamics of the Sachdev-Ye-Kitaev (SYK) model, N strongly coupled fermions with q-body random all-to-all interactions, coupled to a Markovian environment through jump operators either linear or quadratic in the Majoranas. We developed a dynamical mean-field theory for the Lindbladian time evolution on the Keldysh contour and solved the saddle-point equations, numerically for q=4 and analytically for q=2 and large q. For strong dissipation, the system relaxes exponentially to its steady state at a rate linear in the coupling, characteristic of a dissipation-driven relaxation. However, for weak coupling, there are oscillatory corrections to the exponential relaxation and we observe an anomalously large decay rate with a finite value even in the absence of an explicit coupling to the environment. Remarkably, close to the steady state, the real-time Lindbladian dynamics of this system is identical to the low-temperature dynamics in Euclidean time of a two-site non-Hermitian SYK with intersite coupling. Its gravity dual is similar to a Euclidean wormhole in a near-AdS2 background but with a wrong-sign Schwarzian. It is this configuration, dubbed a Keldysh wormhole, together with quantum chaos, that causes anomalous relaxation. I will discuss the signatures of this wormhole configuration and its differences from Euclidean and traversable ones.

Abstract: TimTrack es el algoritmo de ajuste por defecto de trazas de todos los detectores del proyecto Trasgo. Se basa en un formalismo matricial del método de mínimos cuadrados que incorpora, en único paso, todos los observables que afectan a los parámetros de ajuste. El método es universal y puede aplicarse de forma inmediata a casi cualquier escenario de ajuste de datos, con especial ventaja para sistemas híbridos con medidas de distintos observables. En esta charla se mostrara su aplicación a lo casos lineal, no lineal y con ligaduras así al caso de reconstrucción de vértices y decaimiento de partículas.
